When I see this picture in my head I automatically see a story. What I'm trying to say is that your drawing, I feel a feeling when I look it. It's very successful, dragon, girl, light, colors ... I admire you, I hope to be as good as you someday.
I really appreciate the damage on the dragon. The spears are a lovely touch, showing just how fresh the injuries are and what a dangerous situation the girl's in. Really lends to her innocence and/or level of caring.
I really love how it's so detailed but also easy to look at. The contrast is my favorite though. Like how they both have red but the dragon is red with black and the women is red with white. I don't know how you did it (maybe the way she's holding her arms up and the way the dragon is looking intently on her despite its wounds and the chaos around them) but it's almost as of they're telling each other "I'm here for you."
